Application filed November 24, 1916. Serial No. 133,240.

To all whom t may concern:

Be it known that I, TILLIAM KANE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Boiler Structures, of which the following is a specification.

My invention consists of an improved boiler structure, one object being to provide a boiler structure which may include one or more independent boilers.

Another object of my invention is to provide a sectional base or support for the boilers which can be readily varied so that the number of boilers may be increased or decreased according to requirements.

A further object is to provide a sectional top or hood in which the sections may be taken from or added to according to the number of boilers employed.

A still further object is to so construct my invention that each boiler may be heated by a separate gas burner and that the several parts may be easily and quickly cleaned.

Another object is to so design my improved boiler structure that it will be neat and compact and can be manufactured and sold at a reasonable cost.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a top plan view of my invention with the hood removed and including two independent boilers.

Fig. 2 is a front elevation of Fig. 1 showing the hood thereon.

Fig. 3 is a plan view of Fig. 2.

Fig. 4i is a side View of Fig. 2.

Fig. 5 is a perspective View of one of my improved boilers.

Fig. 6 is a detached perspective view of two of the hood sections shown in Figs. 2 and 3.

Figs. 7 and 8 are respectively front and top views of one type of boiler-supporting plate which I employ.

Figs. 9 and 10 are front and top views of another type of boiler-supporting plate which I also use when two or more boilers are included in the structure.

Fig. 11 is a front elevation of my invention including one boiler.

Referring to Figs. 1 to 10 of the drawings, 1 represents the base or boiler-support which has end sections 2 and 3. These sections are preferably made of cast metal and have angularly disposed surfaces -1 and 5 provided with recesses 6 and 7, preferably at their bottom edges.

Each of these side plates has a ledge 8 projecting inwardly from their inner surfaces, and a portion of the web of these plates extend upwardly a short distance from said ledges 8 as illustrated at 9 in Figs. l and-2.

When two or more boilers, as shown at 10 and 11, are included in the structure` front and rear plates 12 and 13 are con nected to the end section 3. The plates 12 and 13 are substantially similar with the exception that the plate 12 has a large opening 141, while the plate 13 has a comparatively small opening or recess 15.

Each of the plates 12 and 13 has an ofi'- set extension or flange 16 which engages the inner surface of the respective portions 17 and 18 of the end section 3, and bolts 19 and 20 extend through the extensions 1G and the portions 17 and 18 to thus secure the plates 12 and 13 to the end sections and so that the outer surfaces of the plates 12 and 13 are flush with the outer surfaces of the portions 17 and 18. Furthermore, each of the plates 12 and 13 has a ledge 21 which is of the same height as the ledges 8 of the end sections 2 and 3.

Each of the plates 12 and 13 has an extension 22 which extends beyond a rib 23, the latter being formed on the inner surface thereof. These extensions 22 are flush with the outer surface of the respective plates 12 and 13. Other boiler supporting plates 24 and 25 are positioned respectively at the front and rear and are included in the base 1. These plates 241 and 25 are of substantially similar construction with the excep` tion that the plate 24 has a large opening 26 while the plate25 has a comparativelyY small recess or opening 27.

Furthermore, each of the plates 24 and 25 have off-set extensions 28 and 29 at opposite sides, said extensions being substantially the same as illustrated in Figs. 5 and 6. The

extension 29 is designed to engage the inner surface of the extension 22 on the plates 12 and 13 and bolts 30 pass through the extensions 29 and 22 and thereby secure the frontplates 12 and 24 and the rear plates 13 and 25 together.

The extensions 28 on the plates 24 and engage the inner surfaces of front and rear portions 31 and 32 of the end section 2, and bolts and 34 secure said extensions 28 to the end section 2, so that the outer surfaces of the portions 31 and are substantially flush with the outer surfaces of the plates 24 and 25.

Each of the plates 24 and 25 has an in wardly projecting ilange which forms a ledge below the upper edges of said plates, and the ledges 35 are on the same level with the ledges 21 and 8 of the plates 12 and 13 and end sections 2 and 3. These ledges t'orln a support for the boilers 10 and 11 and the ledges 8 also form a support for side panels 36 and 37. These side panels adjacent their upper ends have outwardly projecting flanges 38 and 39 upon which rest end sections 40 and 41 of a hood 42, said latter sections also having internal ribs 43 and 44 which rest upon the upper surfaces 45 and 46 of the boilers 10 and 11.

rllhe hood sections 40 and 41 are similarly constructed and are interchangeable. Each of these sections is provided with lugs or earsA 47 which are designed to be bolted to lugs or ears 48 on a central hood section 49. Furthermore, each of the sections 40 and 41 has a semi-circular opening 50, and these semi-circular openings 50 are designed to register with semi-circular openings 51 at opposite edges of the central sections 49 to provide holes for the outlet pipes 52 and 53 from the boilers 10 and 11.

In addition, the central hood section 49 has a flanged opening 54 to which may be connected a pipe to carry oii` the products of combustion in a manner hereinafter more fully described.

Each of the sections 40 and 41 has a longitudinally extending lip 55 which extends from its semi-circular opening 50 to one edge as clearly shown in Fig. 4. These lips are designed to engage under the top ot' the central section 49 from the semi-circular openings 51 to one outer edge of the central hood 49. The central hood section 49 is also provided with longitudinally extending lips 56 designed to engage under the end hood sections 40 and 41, and `when the hood sections are connected together, these lips will be in line with the lips 55 and are therefore oppositely disposed from the openings 5() and 51 as clearly shown in Figs. 3 and4. By this construction the same pattern may be used to'cast both of the end hood sections 40 and 41, and when these hood sections are joined together, the undernlying lips 55 and 56 will form a seal for the pa'rtings between the end sections 40 and 41 and the central section 49, said parting being interrupted only at the openings through which the pipes 52 and 53 extend. y

The boilers 10 and 11 are of similar con'- struction and are made of hollow castings having lateral extensions 57 on opposite sides thereoil which are spaced apart to provide flues 58. The end extensions 57 on One side oit each boiler are longer than the intermediate extensions57 as shown at 57a and include tongues 59, and at the opposite side the end extensions 57a are provided with grooves 60 designed to receive the tongues 59 when two of the boilers are placed adjacent as illustrated in Fig. 2, thus forming an interlock for the boilers and also forming a seal to prevent the products oi? combustion from laterally passing out of the central flues 58 through the parting between the boilers 10 and 11. By having the intermediate extensions 57 shorter than the end extensions 57a, additional flue s'pace 58a is provided as clearly shown in Fig. 1.

The flues 58 extend from top to bottom of the boilers 10 and 11 and communicate with the chamber 61 provided by the hood 42 and the space provided by the base 1. Gas or other hydro-carbon burners (not shown) may bc inserted through the openings 14 and 26 'of the plates 12 and 24 re-` spectively and are preferably placed directly below the boilers 10 and 11. Doors 62 and 63 are provided to form a partial closure for the openings 14 and 26 of said plates 12 and 24. rEhe products of combustion pass upwardly through the lues 58 into the chamber 61, and then outwardly through the opening 54. k

When only one boiler' is used, as shownA in 100 Fig. 11., I dispense with the plates 12 and 13 and secure the extensions 28 and 29 of theV plates 24 and 25 directly to the end sections' 2 and 3, since it will be noted that as above described, the extensions 28 and 29 are simi- 105 lar and are oft-set. The hood may be made in two sections as shown at 64 and 65,khaving portions which provide an outlet 66 'for the products of combustion and registering semi-circular openings 67 for the outlet 11e pipe 52.

1f` it is desired to provide astructure including three or more boilers, a plate 12 and a plate 13 1s added for each additional boiler, it merely being necessary to discon- 11.5

nect the bolts 19 and 2O and to move the end sections 3 away from the plates 12 and 13 to permit the insertion or" two other plates 12 and 13 which are connected respectively to the end sections 3 and to the first-mentioned' 120- plates 12 and 13. 1

It will thus be noted that any number ot boilers may be provided which are. in no way connected to each other within the boiler structure, so that they are free to efqiand` v without injury to anyof the other parts. 1t will be. noted that as the boilers are increased in number, the hood sections may be increased in number either byproviding" additionalcentral' sections 49 or in forming sepa- 130y lll' manera rate sections without the additional flue openings 54. j

By my improved invention, I do away with the connecting of boilers or boiler units by coupling nipples as heretofore was customary, since it is well known in the art that different boilers or boiler units expand in different manners, and the coupling nipples heretofore employed often became loosened or fractured, thus injuring the structure. lherefore, with my invention I provide a boiler structure in which each of the boilers is independent of other boilers in the construction, but have a unitary mounting which may be readily varied to permit other' boilers to be added thereto or taken therefrom.

Each of the boilers in the present instance is provided with an inlet opening GS for return steam or water and in the several drawings l have illustrated these openings as being located adjacent the bottom portion and in the back of the boilers. However, it will be understood that these return openings may be located in any portion of the boiler according to the requirements of the boiler.

lhile l have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence do not limit myself to the precise construction set forth, but consider that am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
